To boot your encrypted disk from the Mac OS Xboot media

1. Insert your Mac OS X CD.

2. Boot to your Mac OS X CD.

3. Do not install Mac OS X; instead, from theUtility Menu, select "Terminal."

4. Type the following command:

diskutil list

You will need to note the disk identifier forthe boot partition for your system disk. The boot partition is named "Boot OS X" and is thepartition immediately following your system disk. For example, if your systemdisk is disk0s2, youshould find a boot partition with the name "Boot OS X" with the identifier disk0s3.

5. Type the following command:

diskutil mount <bootpartition>

Where <bootpartition> is the disk identifier you learned from issuing the previouscommand. This will mount the boot partition for your system disk.

Example: Diskutil mountdisk0s3

6. Navigate to the CoreServicesboot directory. This directory is located at thefollowing path:

cd "/Volumes/Boot OS X/System/Library/CoreServices"

If this directory does not exist, you may needto recover your disk.

7. Copy pgpboot.efi to boot.efi. To do this, typethe following command:

cp pgpboot.efi boot.efi

If this command fails, you may need to recoveryour disk

8. Select Terminal > Quit Terminal.

9. Select Installer > Quit and choose to restart. You should now see thePGP passphrase prompt and if you successfully enter your passphrase, yoursystem will boot correctly.
